United States Patent Filed Aug. 7, 1959, Ser, No. 832,307 6 Claims. (Cl.16"-105) This invention relates in general to hardware, and moreparticularly to improvements in sliding door hanger assemblies utilizedfor mounting a door or panel on a supporting track.

Hanger assemblies to support sliding doors or panels for movement alonga track are generally known in the art; such normally including sometype of mounting bracket means ordinarily attachable adjacent one end ofa door to be supported and having one or more rollers for engaging anormally horizontal overhead track. Usually, two such hanger assembliesare used for each door, one near each upper corner. If the alignment ofthe hanger assemblies and the door jamb is closely supervised,the doorideally will lie in a generally vertical plane with its lateral edgesplumb with the vertical or 'side jamb members. Such ideal installationsare seldom if ever achieved or maintained, however, without adjustingthe door alignment, particularly in new buildings which are prone tosettling. It is especially desirable, therefore, to provide means foradjusting the door relative to the door jamb and track. AThis may beaccomplished conveniently by embodying adjustment means in the hangerassembly for repositioning the door, as is intended by the presentinvention.

Previous inventors havepresented hanger assemblie embodying a widevariety of means for accomplishing the aforementioned objective, but ithas been our experience that such prior devices generally have beenineffective for one reason or another. One familiar type, for example,requires repositioning movement of the entire hanger assembly,particularly the mounting bracket, relative to the door. This manner ofaccomplishing the needed adjustments is lunduly cumbersome and producesexcessive wear of the fastener means and its connection vwith the door,eventually resulting in an insecure mounting for the assembly, which isincapable of maintaining a desired position of door adjustment. As aresult the problem of maintaining a sliding door in proper alignment andposition for accurate and smooth operation has remained as a serious oneto the user.

The present invention meets this problem by providing an improved hangerassembly including an improved means for adjustably positioning thetrack-engaging rollers thereof relative to a related door. In brief,this invention comprises a mounting bracket adapted to receive screwattachment means for fixing the same stationarily to one face of a dooror panel member to be supported for sliding movement along an overheadtrack. A hanger bracket, carrying roller means at its upper end forengaging the track, is juxtaposed between the `mounting bracket anddoor, and adapted for sliding movement relative to the latter betweenpredetermined Adjustment means, carried on the mounting bracket,comprises a rotatable eccentric pin means which engages an opening inthe hanger bracket for rectilinearly reciprocating the latter relativeto the mounting bracket and door, thereby achieving an infinite numberof adjusted positions for the roller means relative to For maximumconvenience, the eccentric means is accessible for operationalengagement at one face of the mounting bracket and may be rotated byusing a screwdriver or like tool. A locking means is also provided forholding the mounting and hanger 2,999,267 vPatented Sept. 12, 1961brackets together and for locking the same at selected positionsof-relative adjustment, determined by the operation of the adjustmentmeans. I The main object of this invention is to provide anew andimproved hanger assembly for use in mounting doors or like panel membersfor movement along a track. Another object of this invention is toprovide a hanger assembly as aforesaid which embodies improved means forits adjustment. f f

An additional object of this invention is to provide a new and improvedhanger assembly which embodies'improved means for adjustablypositioning, plumbing, and aligning a sliding door in a door opening;the door normally being suspended from an overhead track by a paix' ofsuch assemblies.

Another important object of this invention is to provide a hangerassembly which is adjustable to align'a related door as aforesaid,without requiring vadditional means for holding or supporting the doorin the desired position while such adjustment is carried out.

A further object of this invention is to provide a new and improvedhanger assembly for suspending sliding doors from an overhead trackwhich employs a rotatable eccentric means for adjustably positioning therollers of the hanger assembly relative to the upper end of anassociated door for the purpose of adjusting the position and alignmentof the door in a related opening. y Still another object of thisinvention is to providea new and improved `hanger assembly as aforesaidwhich in addition to the said adjustment means also includes means forlocking the assembly in selected positions of adjustment.

A still further object of this invention is to provide a new andimproved hanger assembly embodying improved features -of adjustability,convenience, and simplicity of manufacture and operation.

The above and further objects, features, and advantages of thisinvention will appear to those familiar with the art from the vfollowingdetailed description of preferred and modified forms of the invention,illustrated in the accompanying drawings.

Atypical sliding door v.installation is villustrated .in FIGURE 1,showing the general operational features and modebf employinghangerassemblies according to thxsrnventlon. In bypassing doorlinstallations .as Vshown therein, -two doors -10 andfll are-normally`guided at their bottom endsto move in parallel ver-ticalplanes alongtheparallel paths defined by overhead track mee-ns 14 from which they aresuspended by hanger assemblies 12.and 12'. YBrielyfeach of two slidingdoors 10 `and 11, aligned in parallel vertical `planes yastherein shown,is equipped with a pair of hanger assemblies 12,12' accord* ing to thisinvention; one `such assembly being located adjacent each uppercornerand topfedge 13 of the door or panel 10, tor instance. The twohangerassemblies 12, 12' on door 10, therefore, constitute the onlymeans connecting and supporting the door from overhead track 14, thelatter of which is mounted substantially horizontallyacross the upperend of thedoor-` opening as deined by Sl'llOfllral frame and iambmembers.indcatedgenerally by numeral 15 in FIGURE 1,

-With'refcrence to-FIGS. 2f-5 ofthe-drawing.- it will be recognizedVVand understood that a flrst form ofi hanger essen-:bly i12. `istherein illustrated which includes va mounting bracket 20, acooperatinghanger bracket indic-ated ygenerally by the numeral '21,adjustment-means 22 associated withvboth brackets `20. and 21, andlocking means -23 for fixing brackets Ztl and ,-21 in desired positionsof adjusted -movemenbas determinedby-operation of adjustment means 2 2.The details of the various elements and means m-2.3 will nowbefset outalong withtheir related appurtenances.

Mounting bracket-20 is preferably stamped Afrom sheet metal orlikematen'al to include apair of coplanar aligned `lateral.mounting-llange. portions 25,--25- flanking a central body portion 26thereof; the latter comprising n generally rectangular plateA set outfrom theplane of flange portionsziy -25 and further distinguished by-aCentral offset, or raised longitudinal-:platform portion 27. '4l-'hebody portion alsoY has a pair of ears-28,2Sfextending vat right anglesthereto, one at each-of its upper corners,

and comprising integral extensions of sidewall portions-29, 29 whichdene the laterallimitsof Ithe .bodyportion 2.6. Walls 2.9, 29 arelater-ally spaced --and perform as -guideways for locating and pilotingthe hanger bracket 2:1 for rectilinearl reciprocating movement behindthe `main body portion 26, as will presently appear. The ears 2Sarefparticularly `utilized to locate the mounting-bracket 20 at adesired upright position 'pat the-upperendof the door 10; such earsextending overand engagingthe upper end 13 od the door (seerFlGVZ).

The mounting flanges 25,. are'eachsuitably provided with a centralopening receptive of fasteningmeans, such as a wood screw 30. Thus, withthe location of the mounting bracket 2.0 over one face 31 of the door,land in an upright position set by the locating ears 28, 28, fasteningbracket 20 to the door 10 is easily accomplishedrby passing the woodscrews 430, 30, or like fastening devices, through the openingsV inV themounting brackety portions 25 for threading engagement with the doortherebeneath. It is a feature of this invention thatA once'so Xedinposition, mounting bracket 2b neednot thereatter be removed or thereinto accomplish any-desired kadjustment;of the hanger bracket Z1, whenplumbingand aligning the door in' the jamb 15.

'd wise of the mounting bracket =for cooperation with a locking means23, such as a screw having a slotted head 34 adapted to receive theblade of a screwdriver or like instrument.

'Ilhe shank of the locking screw extends through the slotted openingf`33Yofthe mounting kbracket andthreadingly Vengages `,the ywall .of anopening 35 inthe hanger bracket 21, as viewed best in FIG. 4. With thisarrangement, the renlarged head 34 of the locking means 23 is adapted toengage the sloping'sidewalls of opening 33 to ifrictionally pull thehanger bracket to the mounting bracket at desired. adjusted positions ofrelative movement thereof as will =be described.

Platform portion 27 also includes an enlarged circular opening 38 belowslot 33 through which a circular head portion y40 of the adjustmentmeans 22 projects; said head end also having aslotted opening 41receptiveof a screwdriver blade or the like, used to operate theadjustment means V22. It will be recognized additionally that the lowerendof .the platforml portion 27V is formed with a semi-circular wallportion 43. This accommodates and provides a guideway for thecircular-shaped lactjusti'nent means V22, especially as the latter isrotated.

As best-seen itl-FIGS. 3 and 4, thehanger bracketll is'stamped orotherwise .formed toV include a main body portiondt whichlbears aprofile conguration conform, ing to the main' bodyportion 26 of themounting bracket; Such body portion 45 is provided with-an elongatedoval opening 46 symmetrically aligned on the longitudinal center lineofthe body portion 4S and generally located yto one side of the .lattersmidpoint. Opening` 46 is further aligned with its longitudinal anistransverse to the length- `wiseeuiis of body portion .45 so that. it maycooperate with the adjustment .means 22, as will be described.Additionally, the upper end of Ythe body portion d5A is turnedinwardlyatan angle to `form an inclined arm portion@ which is adapted to overhangtheupper end 11i-ofthe. door, all in the manner best seen inFlG. 4.v-Arrn portion 47 further informed integrally -with la substantiallyvertically extending upper linger portion .48 whichapproximatelyparallels the plane of the brackets body portion 45 and isprovided .for the purpose of supporting connection with a single rolleror a crossarm assembly 50 associated with multiple rollers. .It Will beseen that the` main body portion 45, the inclined arm, portion 47, andthe linger portion 48 of the hanger bracket, are ribbed by parallelextending raised projections or ribs 51, 51 integrally joined at theirone end with a raised island section 52 formed near the upper end of thebody portion 45 Vand containing threaded opening 3S which cooperatesvwith the locking means 23. Such rib and islandconguration adds strengthand rigidity to thehanger bracket and particularly reinforces theinclined arm portion -47 which offsets the main body and cross-armassembly 50.

Thecross-arm-assembly 56 includes, as its lname Virnplies, a cross-armmember 5S pivotally attached at its midpoint to thehanger bracket fingerportion 48 by a single central rivet 516 or other suitable connectingdevice. The cross-arm 55 is preferably offset centrally to receive theextending linger portion 48 of the hanger bracket and provides, adjacentits opposite ends, a pair of coplanar end portions 57, 57 adapted eachto support a rotatable roller wheel 6i). The Wheels Sli are preferablymade of nylon or a similar substance having good wearability andconfigured especially to engage and roll along a bottom rail troughportion 61 of the overhead track member 14. This provides a rolling ormovable support connection between the overhead track and the door 10,as desired. To prevent violent or extreme pivotal activity of thecross-arm assembly 55 about its pivot 56, a'pair of projecting buttons62, 62 are provided, one extending outwardly of each cross-arm endportion 57, to engagethe upper end'63 of the hanger brackets aangaatinclined arm portion 47. Location of the buttons 62, 62 is selected toprovide a desired rotational tilting or :Boating action for thecross-arm of less than 360 rotation.

To hold the hanger bracket 21 in its desired assembled relationship withthe mounting bracket 20, the locking screw means 23 is employed; suchbeing riveted over at its inner end "65 (see FIG. 4) behind the islandsection 52, thereby preventing its dissociation from hanger bracket 21while providing threaded movement along the threaded opening 35.Clockwise rotation of screw means 2'3 serves to draw the raised islandportion 52 tightly against the opposing inside face 68 of the mountingbracket, frictionally locking the hanger and mounting bracket together,pressing opposing facial areas of said two brackets against theadjustment means 22 to lock the latter as Well. Conversely, unthreadingscrew means 23 releases the two brackets and adjustment means when it isdesired to adjust the hanger bracket and rollers 6i) relative to themounting bracket.

The adjustment means 22 in the preferred form of hanger assemblyillustrated in FIG. 2 comprises a substantially cylindrical disc ofnylon or like material capable of being machined or moulded and havingfeatures of good wearability and a coecient of friction suicient toprevent its free rotation over the adjacent contacted surfaces andopposing areas of the brackets 20 and 21 between which it is mounted.While the formation of the adjustment means 22 is generally disc-like, acylindrical eccentric pin portion 70 projects from the rearward face 71of its main cylindrical body portion 72. This projecting pin 70 isadapted to enter and cooperate with the elongated transverse opening 46of the hanger bracket; and to that end is disposed off-center, oreccentrically, with respect to the central axis of the body portion 72.It will be recalled that the projecting head end 40 of the adjustmentmeans extends, from the frontal face of the body portion 72, intoopening 38 formed in the mounting brackets central platform portion 27.Rotation of the body portion 72, effected by engaging slot 41 of headportion 40 with a screwdriver or the like, results in the rectilinear-4reciprocating displacement of the hanger bracket as the pin follows acircular path according to familiar principles.

Due to the frictional interference of the projecting member 7u and thesidewalls of the slotted opening 46, however, as well as the interfacialengagement between adjustment means 22 and adjacent bracket faces, freerotation of the adjustment means is deterred. This is particularly truewhen the load of the door is on the hanger assembly. Therefore theeccentric may readily be rotated to an infinite number of adjustmentpositions to correspondingly adjust the position of the hanger bracketand rollers 69 relative to the mounting bracket, as selected. Thereafterthe locking means 23 may be operated to maintain the adjusted positionof the hanger and mounting brackets. Thus the door 19, equipped with twoassemblies 12, 12', may be plumbed and aligned in the doorway opening inan easy, convenient, and improved manner by adjusting either or bothassemblies 12, 12' as needed.

Turning now to the modified hanger assembly 79 illustrated in FIGS. 7-9of the drawings, it will be recognized that such is generally simplifiedover assembly 12 above described, yet without loss or sacrifice of theessential and desirable features of this invention. For instance,assembly 79 does not employ the particular locking screw means 23 ofassembly 12, yet the necessary lock ing function is provided for inassembly 79. Also, the dual rollers 60, 69 and related cross-arm 50 havebeen removed from assembly 79; the same being replaced with a single,track-engaging roller means. With few exceptions, assembly 79 otherwiseclosely parallels the .elements and features of hanger assembly 12.l

Mounting bracket 86, like bracket 20 of assembly 12,

is preferably stamped of metal to provide a pair of coplanar alignedlateral mounting flanges 85, flanking a central body portion 86. Thebody portion 86 is set out of the plane of the flanges by transverselyrelated interconnecting wall portions 87, 87 (shown in crosssection inFIG, 6), each llanked at their opposite endsby short ear extensions ofthe mounting arms, indicated at 88 and 88a. These extensions provideguideways tov pilot the hanger bracket 81 as the latter rectilinearlyfreciprocates between walls 87.

Mounting flanges 85, 85 are each suitably provided-` with a centralopening receptive of fastening means such as screw means 83, whereby thebracket 8l) is easily attached to one face of door 10 adjacent an uppercorner thereof, as in assembly 12 of FIG. l. The body portion 86 isprovided with a central circular-v opening S9 through which a circularhead portion 90 of the adjustment means 82 extends. In this regard suchbody portion is adapted to superpose a portion of the hanger bracket 81as the latter reciprocates in response to operation of the adjustmentmeans.

The hanger bracket, as seen best in FIGS. 6 and 7, is formed with thegenerally rectangular body portion 91 which is adapted to be positionedupright in operating assembly between walls 87, 87 and the guide ears88, 83a of the mounting bracket. An elongated oval opening 92 isprovided in body portion 91, symmetrical of the latters lengthwise axisand generally to one side (above) the midpoint thereof. Opening 92further is aligned with its own lengthwise axis transverse to'thelengthwise axis of the hanger bracket, thereby to cooperate withadjustment means 82.

The body portion 91 is also angled inwardly at its upper end to providean inclined arm portion 93, adapted to overhang the' upper end of door10 in operation. The outer end of arm portion 93 is formed with anintegral linger portion 94 extending in an offset plane paralleling theplane of body portion 91. Parallel raised Vreinforcing ribs 95, 95strengthen both portions 93 and 94, with the latter serving to directlysupport a single rotatable track-v engaging roller means 96. To thislatter end, roller 96 is rotatably carried on a rivet axle 97 tixedtransversely to the bracket finger portion 94 (see FIG. 7). It will beunderstood that adjustment of the roller means toward and away from theupper end of door 10 depends on and occurs with the operation ofadjustment means 82. to move the hanger bracket.

Adjustment means 82 is similar in all respects of structure andoperation with adjustment means 22 of the previously descri-bed hangerassembly 12. Thus the same comprises a generally cylindrical form havinga disclike body portion 99 from one end face of which eX- tends thecoaxially aligned head portion 90. An eccentrically disposed pin portion100 projects from the opposite end face of the body portion and isreceived in the elongated opening 92 of the hanger bracket. Thisarrangement serves to produce rectilinear reciprocating movement of thehanger bracket in response to rotation of the adjustment means; headportion 90 of the latter having a slot 101 receptive of a screwdriverblade for the purpose of engaging and rotating the adjustment means.Thereafter operation of locking means 83 maintains a desired adjustedposition for the brackets 80 and 81.

More particularly, the locking means 83 operates in the mannerillustrated in FIGS. 8 and 9 to hold the assembly in operating positionand selectively lock the adfi1stn1-entf meansY and? bracketstogeth'enAsf therein shown; screwJ means@ 83;' 835 are; threaded into the` door stbermounting bracketand'v-the body portion 99-of the adjustment'means;Asfshownvin FIG.- 8, walls'87A in` tentionallyare of'insucient depth ordimension to permitfface- 162 ofthe mounting flanges S5 to lie iiushwith face 163 of the hanger bracket when the adjustmentmeansgparticularl'y body portion 99Ythereof, is'assembled between thetwo brackets."
